LOCOMOTIVE.

and useful Invention in Locomotives; and .I declare the following to be a full, clear, and

exact description of the same, such as will enable others skilled in'the art to'which it appertains to make anduse the invention, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 is a side View of the invention as applied to a locomotive. Fig. 2 is an end View of the invention as applied, with one of the pipes leading to the steam cylinders removed and with the locomotive parts shown in section. Fig; 3 is a section on the line 3-3, Fig. l, with parts broken away. Fig. 4 is a similar view showing a modification.

The invention relates to pipe joints and is particularly designed for the steam pipes at the front end of a locomotive which connect the boiler -ivith the cylinders.

The invention consists in the novel construction and combinations of parts as hereinafter set forth.

In the accompanying drawings, illustrating the invention, the letter a, designates the horizontal steam pipe leading from the boiler and having a 'i joint connection 6, with the downward extending pipes c, 0, leading to the steam cylinders. It has been found in practice that the joint connections iii the pipes'c, 0, with the T-joint b, and at the bottom at c, c, with the connections (Z, (5, running to the cylinders, are liable to become strained through the expansion and contraction of the parts, added to the great vibration to which they are subjected, resulting in leakage of steam, which be it ever so slight, owing tothe great steam pressure, affects materially the steaming power of the locomotive. In order to avoid this objec- Speeification of Letters Patent.

or hell of the joint. This connection in the drawings, Fig. 3' is shown as a direct screw connection, although it may be made by means ofbolts if desired, as shown in Fig; 4. The neck portions e c of the balls are secured to the steam pipes c, c,'at e, e.; The T-joi'nt connection 6, may be further provided at its connection with the boiler pipe a, with an expanded cup or hell portion if, in which fits the hollow ball f, extending rom and having its hollow neck portion communicating with the boiler pipe, providing an additional universal joint connection the details of which are the same as above ex plained for the other universal joints, all of which are made of such metal or material as may be found best. In this way not only will all objectionable expansion and contrac tion, vibration or other movement whatsoever taking place at any of the joints between the dry pipe a and the cylinders be taken up, but the di culty of making the.

steam pipe connections between the T-joint and the steam cylinders will be done away with by the universal joint connection be tween theT-joint and the boiler pipe, which allows the T-joint to be moved so as to shorten or lengthen the distance between the cylinder and the same.

By the use of the applicants inveiition plain all-metal steam joint connection may be used at c, c, at the bottom of the steam pipes leading from the T-joint. Many incidental advantages will also result, as

avoidance of expense, and loss of time in repairing the leaks when the locomotive, which is practically put out of commission, must be sent to the shops, loss of tonnage on account oi the locomotive not being able to haul its full eupacit, and time saved in putting in the steam pipes in the front end or the locomotive.

Having thus described the invention, what I claim new and desire to secure by Letters Patent is:

in a locomotive, the combination with a boiler having a rigid steam supply pipe, stean'l cylinders, and connection pipes e tween said steam supply pipe and said cylinders, of means fortaking-up vibration and expansion and contraction comprising a band surroiuiding the end of said steam supply pipe and having-a tapered end,.a hollow ball having a stem provided with a tapered'l end fitting against. the tapered end 1 having :iieo movable steznntight engagement 10 of said hand, means connecting the stem of with said opposite bails.
